Issue in dimming with SpaceLogic MTN6710-0102

[chetan]

We are facing issue with Spacelogic MTN6710-0102 dimmer. System working fine for 3-4 days & then button configuration on MTN627819 keypad changes automatically. Also, in some of the DB’s we get red indication on the dimmers and keypad stops working. Please note that after programming system runs trouble free for 2-3 days. (ETS Version ETS6.0.6)

Hello Chetan!
Pretty intersting/strange behaviour 🤔
Just to make sure ... after ETS-Download Dimmer and and PB works as they should.
Means you can dim your lights and switch them on/off via the PB for some days without having the red LED activ on the dimmer.
Then something happens ... the dimmer goes in error mode and the PB looses his configuration.
You download again the ETS-Applications and then it works again for some days?
Is it like this?

Is this cabinet installed within an industrial environment where some heavy machines are working? 

Can you please provide more detailed information of the dimmer by the use of the DFU-Tool?
There is a diagnostic functionality included which generates a certain report.
Here the links to the tool and documentation of the tool in case you do not use it already.
